I just paid 2979 EGP in tax on an AONE4 ticket ex-CAI written on AA stock. ReelChief paid 5880 EGP in taxes on his AONE4 ticket ex-CAI on BA stock.

I have been told anecdotally that the fuel surcharges are determined by the ticketing airline, rather than by airline chosen for each sector.

Your daughter should be able to switch airlines on any sector on her ticket at no cost after ticketing. Thus, she should be able to switch her MEL-AKL flight now written on AA back to QF. I flew AKL-SYD last month, using a ticket coupon for LA. QF excepted it without even a stop at their ticket counter.

Also, she should have been given a detailed breakdown of the fees that she paid. This is important when she is traveling, should an airline want to see if a country's exit tax has been paid (for example). LAN is particularly vigilant about this. For the ticket I've just picked up, I have a breakdown of the fees I've paid stapled to each coupon receipt - a very useful practice by the agent.
